*A filter is required for each return − air inlet. Airflow performance included 3/4 − in. (19 mm) washable filter media such as contained in factory − authorized accessory filter
rack. To determine airflow performance without this filter, assume an additional 0.1 in. w.c. available external static pressure.
−− Indicates unstable operating conditions.

* Cubic ft. of natural gas per hr for gas pressures of 0.5 psig (14 − in. w.c.) or less and a pressure drop of 0.5 − in. w.c. (based on a 0.60 specific gravity
gas). Ref: Chapter 6 ANSI Z223 − 2012/NFPA 54 − 2012.
Piping should be pressure and leak tested in accordance with
NFGC in the United States, local, and national plumbing and
gas codes before the furnace has been connected. After all
connections have been made, purge lines and check for
leakage at furnace prior to operating furnace.
If pressure exceeds 0.5 psig (14
− in. w.c.), gas supply pipe
must be disconnected from furnace and capped before and
during supply pipe pressure test. If test pressure is equal to or
less than 0.5 psig (14 − in. w.c.), turn off electric shutoff switch
located on furnace gas control valve and accessible manual
equipment shutoff valve before and during supply pipe
pressure test. After all connections have been made, purge
lines and check for leakage at furnace prior to operating
furnace.
The gas supply pressure shall be within the maximum and
minimum inlet supply pressures marked on the rating plate
with the furnace burners ON and OFF.
